DETAILED DESCRIPTION
The following describes in detail embodiments of the present
application. Examples of the embodiments are shown in the
accompanying drawings, where reference signs that are the same or
similar may represent same or similar components or components that
have same or similar functions. The following embodiments described
with reference to the accompanying drawings are exemplary, and are
intended to describe the present application and not to limit the
present application. Rather, the embodiments of the present
application include all changes, modifications and equivalents
falling within the spirit and scope of the appended claims.
FIG. 1 is a flowchart of a train door control method according to
an embodiment of the present application.
Referring to FIG. 1, the train door control method includes the
following steps:
Step S11: Acquire a first train identifier and a second train
identifier when multiple trains park on a platform at the same
time.
A door of a first train to which the first train identifier belongs
is to be opened at a current time point, and a second train to
which the second train identifier belongs is a train arranged after
the first train, which enters the platform and parks on the
platform.
Since doors of trains are controlled by unified control
instructions in the related art, there is a lack of flexibility,
and it is not suitable for situations where platform doors and
train doors do not match. For example, when one platform has a
unified direction, and two trains A and B park thereon at the same
time, doors of the trains A and B need to be controlled separately,
and the operation efficiency of the trains is low.
An example is shown in FIG. 2. FIG. 2 is a schematic flowchart of a
train door control method for a single train according to an
embodiment of the present application. PSL is a local control
panel. As can be seen from FIG. 2, the train door control method
for the single train has a safety strategy such as door opening,
closing and locking, which can ensure the safe operation of the
train. It is to be noted that values 4.5 s, 5 s, and 3 times shown
in FIG. 2 are only used as examples, and are not limited by the
present application.
In the embodiment of the present application, external professional
interfaces such as an independent logic control circuit board and
signal system SIG and a local control panel PSL are used to
transmit signals. When one of the interfaces fails, the normal
operation of the other interfaces is not affected. Therefore, in
the maintenance of related faults, the normal running of the system
and the operation of the train cannot be affected, and by
controlling each train door and platform door separately, multiple
trains can park on one platform, which can ensure the safety of
train operation, improve the operational efficiency of trains and
improve the flexibility of the train door control method.
In an embodiment of the present application, the first train
identifier is used to uniquely identify the first train and the
second train identifier is used to uniquely identify the second
train.
In a specific implementation, when multiple trains park in the
platform at the same time, specifically, when a stop position of
the first train at the platform is accurate and the door of the
first train is to be opened at the current time point, the logic
control circuit board and signal system SIG acquires a first train
identifier to trigger a first opening instruction for opening the
door of the first train; and after the second train stops steadily
and accurately after the first train, the logic control circuit
board and signal system SIG acquires a second train identifier to
trigger a second opening instruction for opening the door of the
second train.
S12: Control the opening and closing of the door of the first train
and a door of the second train at different time points
respectively according to the first train identifier and the second
train identifier.
Since the first train is arranged in front of the second train, the
logic control circuit board and signal system SIG may first control
the door of the first train to be opened, and control the door of
the second train to be opened after a period of time, so that the
operational efficiency of trains can be improved under the premise
of ensuring safety.
Similarly, the logic control circuit board and signal system SIG
may first control the door of the first train to be closed, and
control the door of the second train to be closed after a period of
time. By controlling doors of multiple trains respectively, there
is a before-after related logical relationship therebetween, which
can guarantee the personal safety of passengers and improve the
operational efficiency of trains based on the premise of ensuring
the driving safety of trains.
Further, a first opening instruction for controlling the door of
the first train to be opened may be generated according to the
first train identifier, and the opening of the door of the first
train may be controlled according to the first opening instruction;
a second opening instruction for controlling the door of the second
train to be opened may be generated according to the second train
identifier at a time point of a first preset time interval after
controlling the door of the first train to be opened according to
the first opening instruction; the opening of the door of the
second train may be controlled according to the second opening
instruction; a first closing instruction for controlling the door
of the first train to be closed may be generated according to the
first train identifier at a time point of a second preset time
interval after controlling the door of the second train to be
opened according to the second opening instruction, and the closing
of the door of the first train may be controlled according to the
first closing instruction; a second closing instruction for
controlling the door of the second train to be closed may be
generated according to the second train identifier after
controlling the door of the first train to be closed according to
the first closing instruction; and the closing of the door of the
second train may be controlled according to the second closing
instruction, so as to control the opening and closing of the door
of the first train and the door of the second train at different
time points respectively.
In some embodiments, referring to FIG. 3, step S12 specifically
includes the following steps:
S31: Generate a first opening instruction for controlling the door
of the first train to be opened according to the first train
identifier, and control the door of the first train to be opened
according to the first opening instruction.
In the embodiment of the present application, the first opening
instruction is used to control the door of the first train to be
opened, and the first opening instruction may be triggered by the
logic control circuit board and signal system SIG.
Specifically, when the door of the first train is to be opened at
the current time point, the logic control circuit board and signal
system SIG may generate a first opening instruction for controlling
the door of the first train to be opened, and control the door of
the first train to be opened according to the first opening
instruction. Then, the door of the first train is opened, and
passengers get on and off the first train.
S32: Generate a second opening instruction for controlling the door
of the second train to be opened according to the second train
identifier at a time point of a first preset time interval after
controlling the door of the first train to be opened according to
the first opening instruction.
The first preset time interval may be set by related technical
staff of a train control center, or the first preset time interval
may be set by a driver of the train. This is not limited
thereto.
In the embodiment of the present application, the second opening
instruction is used to control the door of the second train to be
opened, and the second opening instruction may be triggered by the
logic control circuit board and signal system SIG.
Specifically, the logic control circuit board and signal system SIG
may generate a second opening instruction for controlling the door
of the second train to be opened at a time point of a first preset
time interval after the logic control circuit board and signal
system SIG controls the door of the first train to be opened
according to the first opening instruction. The orderly operation
of trains when multiple trains park in the platform at the same
time can be ensured.
S33: Control the door of the second train to be opened according to
the second opening instruction.
Specifically, the logic control circuit board and signal system SIG
controls the door of the second train to be opened according to the
second opening instruction. Then, the door of the second train is
opened, and passengers get on and off the second train.
S34: Generate a first closing instruction for controlling the door
of the first train to be closed according to the first train
identifier at a time point of a second preset time interval after
controlling the door of the second train to be opened according to
the second opening instruction, and control the door of the first
train to be closed according to the first closing instruction.
The second preset time interval may be set by related technical
staff of a train control center, or the second preset time interval
may be set by a driver of the train, which is not limited
thereto.
In the embodiment of the present application, the first preset time
interval and the second preset time interval may be the same or
different.
In the embodiment of the present application, the first closing
instruction is used to control the door of the first train to be
closed, and the first closing instruction may be triggered by the
logic control circuit board and signal system SIG.
Specifically, the logic control circuit board and signal system SIG
may generate a first closing instruction for controlling the door
of the first train to be closed at a time point of a second preset
time interval after controlling the door of the second train to be
opened according to the second opening instruction, and control the
door of the first train to be closed according to the first closing
instruction. Then, the door of the first train is closed and
locked.
S35: Generate a second closing instruction for controlling the door
of the second train to be closed according to the second train
identifier after controlling the door of the first train to be
closed according to the first closing instruction.
In the embodiment of the present application, the second closing
instruction is used to control the door of the second train to be
closed, and the second closing instruction may be triggered by the
logic control circuit board and signal system SIG.
Specifically, after the door of the first train is closed and
locked, a signal indicating that the door of the first train is
closed and locked is transmitted to the logic control circuit board
and signal system SIG, the logic control circuit board and signal
system SIG allows the first train to depart, the first train leaves
the platform, and when the logic control circuit board and signal
system SIG acquires a signal indicating that the first train has
left the platform, a second closing instruction for controlling the
door of the second train to be closed may be generated according to
the second train identifier.
In the embodiment of the present invention, the logic control
